编译

unzip git-master.zip
cd git-master

yum install openssl-devel curl-devel expat-devel perl-ExtUtils-MakeMaker gettext gettext-libs gettext-devel asciidoc xmlto docbook2X

ln -s /usr/bin/db2x_docbook2texi /usr/bin/docbook2x-texi 

错误

libgit.a(utf8.o): In function `reencode_string_iconv':
/usr/local/git/utf8.c:463: undefined reference to `libiconv' libgit.a(utf8.o): In function `reencode_string_len':

/usr/local/git/utf8.c:515: undefined reference to `libiconv_open' collect2: ld returned 1 exit status
make: *** [git-credential-store] Error 1 

从错误提示看，是缺少libiconv。

安装libiconv

1. 下载编译

   cd /usr/local

   wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz

   tar -zxvf libiconv-1.14.tar.gz

   cd libiconv-1.14

   ./configure –prefix=/usr/local/libiconv && make && make install

2. 创建一个软链接到/usr/lib

   ln -s /usr/local/lib/libiconv.so /usr/lib

   ln -s /usr/local/lib/libiconv.so.2 /usr/lib

3. 然后回到git目录继续编译

   cd /usr/local/git

   make configure

   ./configure –prefix=/usr/local –with-iconv=/usr/local/libiconv

   make

   make install

4. 此时，git应该编译安装成功了，测试如下：

   $ git –version

   git version 2.5.0
